Thyristors - TRIACs are components of integrated circuits or semiconductor materials used to control current or voltage in electronic or electrical circuits. The BCR1AM-8P#B10 is a three-terminal semiconductor switch specifically developed for home electronic and appliance sectors. The model has a low on-state voltage drop, low dV/dt and an RMS current rating of 8 Amps.

The BCR1AM-8P#B10 application fields are mainly for sensored motor drives, lamps and solenoid drivers. Its load AC voltage range from 90 to 264 Vac, and its load AC frequency range from 47 to 63 Hz. The BCR1AM-8P#B10 can also be used in various light-dimming applications such as in dimmable LED drivers and electronic ballast.

The BCR1AM-8P#B10 also has a few notable features such as its high surge current capability—withstanding up to 3500 V DC, zero crossing logic control, positive and negative logic control, a total on-state voltage drop of 1.45 V in the conduction direction. Its zero voltage turn-on characteristics allow for a complete and immediate on/off control of current.

The working principle of a BCR1AM-8P#B10 thyristor is based on a reverse-biased voltage drop; when a positive voltage is applied to the gate, a current flows through the reverse-biased diode and turns on the thyristor.The greater the voltage applied to the gate, the more current will flow and the faster the device will activate. When the voltage reaches the breakdown voltage, the device activates completely and the on-state voltage or the Vce drops. Conversely, when the gate voltage is removed, the device turns off. This turn-off is much faster than the turn-on, as the only energy required to turn off the device is the junction capacitance. This is because the reverse-biased junction no longer allows a current, so the device immediately stops conducting.

The BCR1AM-8P#B10 is an SCR type medium power TRIAC, which is the perfect choice for controlling the speed of AC motor drives, dimmable LED lights and other related applications. It provides a high surge current capability and fast on-off switching. Along with an RMS current rating of 8 Amps and high voltage withstanding, these features make BCR1AM-8P#B10 the perfect component for controlling AC circuits and speed of AC motor drives.
